After installing pulseaudio-equalizer package, Pulseaudio doesn't work anymore. Due to that, no device can be configured glad to KDE's sound widget: https://askubuntu.com/questions/976375/kubuntu-17-10-no-audio-devices-found-no-settings-no-sound
sudo cat /var/log/syslog | grep pulseaudio
[pulseaudio] module-equalizer-sink.c: module-equalizer-sink is currently unsupported, and can sometimes cause PulseAudio crashes, increased latency or audible artifacts.
[pulseaudio] module-equalizer-sink.c: If you're facing audio problems, try unloading this module as a potential workaround.
[pulseaudio] module-equalizer-sink.c: Master sink not found
[pulseaudio] module.c: Failed to load module "module-equalizer-sink" (argument: ""): initialization failed.
Also, "apt purge pulseaudio-equalizer" doesn't remove "load-module module-equalizer-sink" from the .config/pulse/default.pa so it continues to fail at start afterwards.
sudo cat /var/log/syslog | grep pulseaudio
[pulseaudio] ltdl-bind-now.c: Failed to open module module-equalizer-sink.so : module-equalizer-sink.so: cannot open shared object file: No such file or directory
[pulseaudio] module.c: Failed to open module "module-equalizer-sink".
NB: I cannot choose pulseaudio-equalizer as targeted package for this bug as it's not listed despite this:
sudo apt search pulseaudio-equalizer
